Suomi NPP

The NPOESS Preparatory Project (NPP) was renamed to Suomi National Polar-orbiting Partnership (Suomi NPP) in honor of Verner E. Suomi, University of Wisconsin meteorologist, widely recognized as the "Father of Satellite Meteorology."

Launched from California’s Vandenberg Air Force Base a board a Delta-II Mission Launch Vehicle in October 2011, Suomi NPP is the predecessor to the JPSS series spacecraft and is considered the bridge between NOAA's legacy polar satellite fleet, NASA's Earth observing missions and the JPSS constellation. Suomi NPP was constructed with a design life of five years (although it’s still functioning normally).

and carries five state-of-the-art instruments: (1) VIIRS, (2) CrIS, (3) ATMS, (4) OMPS, and (5) CERES FM5.
